I have a time application on my Android phone that I use for RC sailplane flying tasks. The timer is extremely configurable.
For instance, you can set the task for 3m15s and have it ring at 3.15, 6.30, 9.45, etc.
You can also have it sound an alarm a set period before the task ends and then count down the seconds till the 3.15 mark. So you can occupy yourself with other things and then get a 15-second warning to remind you it's almost time to mark the map.
I haven't used this with SH3 yet. But I suspect it'll be perfect for it.
